Letters Patent No. 104,545, dated June 21, 1870.

IMPROVEMENT 1N Sonst.' HAY-RAKES.

The Scheule refer-red to in these Letters Patent and making part of the same.

To all whom tt 'may concern.-

Be it known that I, Lnw'rs S. Bomann, of Grand Rapids, in the county` of Kent and in the State of Y Michigan, have invented certain new and useful Iml provements in Horse Hay-Rakes; and do hereby deolarethat: the following is a full, clear, and exact descriptionr thereof, reference being had to the accompan ylng drawing and to the letters of reference marked thereon making a part of this specification.'

, 'The nature of my invention consists in the combination of the movable rake-teeth with the rakehead, and the arrangement of a cross-shaft with the coil-springs,,secured bya stud, from which extend yflat springs, which bcaragainst the front of the teeth;

also, -iu theconstiuction and arrangement of the parts of' va horse hayfrake, as more fullyI hereinafter set forth. p

In order to' enable othersskilled in the art to which my invention appertains to make aud use the same, I will now proceed to describe its construction vand operation, referring to the'annexed drawing, in which.- Figure 1 is a vertical cross-section of my rake; Figure 2 is a plan view of the same; Figure 3 is aview of an elbow that .pivot-s .rake-head to the frame; and

Figure 4 is a front view of the device for regulating the thills. y v

The frame of my hay-rake consists of two side beams, Al A, connected 'near their front ends by a beam, B, and at their center by another beam, C, from the ends of which latter beam, axles project for the wheels D D. V

`The rake-head E consists of two bars,w and b, con-V nected at their ends by end pieces dici, which rise above the bars a l1', and support, at'their upper ends', anotherbar, e. j

The headA E is hinged to the frame by means of el- .bows ff, the .ends vo t the hars 'a b' resting upon the upper side of the. s ide beams A A near their rear' ends.

. 'lhe elbowslf faresecured to' the vunder Vside of" the har a.and pivoted to the inner sides of 'the bars or beams A. l .'llhe. elbows are provided with .several holes in their ered, so aslto put the points .of the teeth close to the ground, or raise them up, as may be needed.

Under the back partof the head, that is,under the Abar b, through the side beams A A, are set-serews 1g, so asto change the points ofthe teeth ,in any desired positiom- At a suitable point in the rake-head E is a standard or. forked arm, 71, towhich is pivoted `a rod, Gr, thefront end of said rod-being pivoted to a lever, 'H, which, in turn, is 'pivoted at a suitable point in the frame, the' two forming a lock-lever, to mise and lower the rake at will, said lock-lever dropping down at the side of the'drivers seat, J, arranged on the bai IC, as' shown in the drawing.

The rake-teeth I I are sawed 'out in the required circular or curved shape, and faced withiron, i, at the point, and for a suitable distance up along the front side, as seen in iig. 1.

y 'lle usual bent tooth has the serious defect that it .-wiil'not hold its shape. Being exposed to thenveather,

it will straighten out, so as to spoil the'rake entirely` But, by sawing the tooth out in the proper shape, and f acing it with iron, the tooth is strengthened, and prc- ,vented from straightening.

The teeth are attached in the following manner:`

A, flat spring, 7c, is attached to the tooth, on the front side, directly above the upper end of the iron facing, z', said spring being curved, as shown in fig. 1, and its .upper end passing in front of and then 'on top of the 'har a of the rake-head, there it Vis lleld i p0- stion by a'screw, m.

Above the upper end of the spring It, between it and the head of the screw m, is a coil-spring, nf, thus making it a double spring for attaching the tooth.

The upper ends of the teeth Ypass through loops p p, extending from the rear side 'of the bar b, and they then pass up through mortises in the bar e.

The usual single spring has the objection that there is so much labor fort to perform that it cannot do it on uneven ground. With the double spring, the at spring-.lc takes the lirst strain that holds the tooth in position; then, as the tooth is'drawn back, and raised up, it throws the rest of the strain on the coil-spring athereby making it perfectly easy and safe on thedat spring. v. On the front bar- B, at suitable points, are metal loops, fr fr, through which the thills L pass; and under these thills are stscrews, s, s'o'as to regulate them according to the size of the horse; thereby keeping the frame level. Havingthus fully'described my invention, y What I. claim as new, and desire to secure 'by Let ters Patent, isv 1. The combination .of the slotted rake-head E andy I movable Vrake-teethv I, with the cross-shaft a, with lower parts, -so that, by taking out the bolts that pivot them .tothe frame, the head can be raised or low-i studs'm, securing the coilfsprings n, and curved dat springs k, whose ends bear upon the teeth I, all sub- Istantially as set forth.

2. The combination of the slotted rake-head IE, metal-bound teeth I,"elbows f, set-screws-g, shaft a, with springs 'n and lt and levers H G, with'the frame A, all asset forth.

In testimony that I claim the foregoing, I have hereunto set luy/hand this 25th day of-February, 1870.
